How to Build Anything Using Delrin and a Laser Cutter
Need a simple fab process to go from a humble vector graphic to a final part — in a matter of minutes? The CO2 laser cutter might be the right choice. As these tools open themselves up to widespread use through hackerspaces, I decided to give Delrin some well-deserved time under the spotlight.
This guide is a brief collection of tips and techniques that I’ve either learned from others or discovered on my own over the last couple years working with laser-cut Delrin (a.k.a Acetal) for functional prototypes. I hope this guide serves you well as we keep exploring …read more
Why IoT will Fail (and How to Save It)
Buzzword technology has two possible fates: they fail and disappear or they succeed and disappear. Remember at one time “multimedia” and “networking” were buzzwords. They succeeded and now they’ve vanished into ubiquity. Of course, there are plenty of failed buzzwords (like telecosm) that you probably don’t even remember. They just vanished into obscurity.
Unless you’ve been living under the CNC mill in your local hackerspace, you’ve probably heard or read about the “Internet of Things” (IoT). Companies big and small have realized that getting in early on The Next Big Thing is good for share prices and, right now, IoT …read more
The Year of the Car Hacks
With the summer’s big security conferences over, now is a good time to take a look back on automotive security. With talks about attacks on Chrysler, GM and Tesla, and a whole new Car Hacking village at DEF CON, it’s becoming clear that autosec is a theme that isn’t going away.
Up until this year, the main theme of autosec has been the in-vehicle network. This is the connection between the controllers that run your engine, pulse your anti-lock brakes, fire your airbags, and play your tunes. In most vehicles, they communicate over a protocol called Controller Area Network (CAN). …read more
Want to Create a FabLab in your Garage? Start by Joining your Hackerspace
For many hardware enthusiasts, it’s hard to stop imagining the possibilities of an almighty fablab in our garage — a glorious suite of machines that can make the widgets of our dreams. Over the years, many of us start to build just that, assembling marvelous workbenches for the rest of us to drool over. The question is: “how do we get there?”
Ok, let’s say we’ve got a blank garage. We might be able to pick up a couple of tools and just “roll with it,” teaching ourselves the basics as we go and learning from our mistakes. With enough …read more
FCC Introduces Rules Banning WiFi Router Firmware Modification
For years we have been graced by cheap consumer electronics that are able to be upgraded through unofficial means. Your Nintendo DS is able to run unsigned code, your old XBox was a capable server for its time, your Android smartphone can be made better with CyanogenMod, and your wireless router could be expanded far beyond what it was originally designed to do thanks to the efforts of open source firmware creators. Now, this may change. In a proposed rule from the US Federal Communications Commission, devices with radios may be required to prevent modifications to firmware.
The proposed rule …read more
